About Magnus Motorsports


Magnus Motorsports, who we are today, has been 20 years in the making. A Toronto-based speed shop owned and operated by  Marco Passante is most well known for pioneering the 4G63 culture worldwide.

Magnus was built around a philosophy that if we are going to do it, it has to be of the highest quality and it must work to the highest standard. Simply put – make it work, make it look good, make it the best. This philosophy was affirmed many times over when Magnus powered the fastest, most reliable and most powerful 4 cylinders in the world, continuously breaking world records and countless podium finishes in various forms of racing both on the professional and grassroots level. Magnus is responsible for bridging the gap between professional racing and the import car tuner market.

Magnus Motorsports is a full-time fabrication and tuning shop. We have a machine for every job. Our fabrication shop consists of three CNC workstations, two welding stations, two manual bridge ports, two lathes, a surface grinder, and every tool in between, from sheet and tube benders to belt sanders to band saws, to custom made tooling for all of our own products. One lift is in the main shop to fit parts. This serves as our prototype area and an area to build chassis and race cars. Upstairs we have an inspection and design rooms, as well as offices. The main building is primarily used for fabrication and production.  This building also consists of an office area, along with an upstairs design room, where all the parts are designed and measured. It is digitally programmed into CAD. The dyno room has its own service shop in it and is where all the service work is performed. It has an engine room and transmission room and is physically separated from the main shop.

We have served as a research and test facility for some OEM manufacturers. We build machines and contraptions to test various components for longevity or test the component until failure providing a report.

This is one of the main reasons why our engine building skills are so sought after worldwide. With our years of experience and with failure analysis, we have been able to tell you why you may have had a failure and how we can help your race team fix that weak link. Our scope is wide. Our team is not too proud to tackle any job nor are we afraid. We prefer the challenge. We pride ourselves on being able to engineer solutions.

There are always different ways around problems and better ways to solve or improve upon it. We always think away from the norm. We have no boundaries. There are no limits. We do not believe that a ceiling exists or a number we cannot surpass. We approach all projects as a comprehensive engineering challenge. We challenge ourselves to build whatever it is that the project demands. Since 1995, this distinction has been what makes us different. In 15 years, we have continuously explored new horizons and let our passion for the automotive industry guide us.

We are actually one of the few race shops that have the capability to build anything and build it all on the premises. Though we are more of a manufacturer now, we still stick true to our roots and build race cars. Simply said, we do it all in the house to monitor and ensure only the highest quality and most durable product whatever it may be, represents what Magnus Motorsports stands for.
